+/*===============================================================================
+
+    Handling of the classes in the AppCDS archive
+
+    To ensure safety and to simplify the implementation, archived classes are
+    "segregated" into several types. The following rules describe how they
+    are stored and looked up.
+
+[1] Category of archived classes
+
+    There are 3 disjoint groups of classes stored in the AppCDS archive. They are
+    categorized as by their SharedDictionaryEntry::loader_type()
+
+    BUILTIN:              These classes may be defined ONLY by the BOOT/PLATFORM/APP
+                          loaders.
+
+    UNREGISTERED:         These classes may be defined ONLY by a ClassLoader
+                          instance that's not listed above (using fingerprint matching)
+
+[2] How classes from different categories are specified in the classlist:
+
+    Starting from JDK9, each class in the classlist may be specified with
+    these keywords: "id", "super", "interfaces", "loader" and "source".
+
+
+    BUILTIN               Only the "id" keyword may be (optionally) specified. All other
+                          keywords are forbidden.
+
+                          The named class is looked up from the jimage and from
+                          Xbootclasspath/a and CLASSPATH.
+
+    UNREGISTERED:         The "id", "super", and "source" keywords must all be
+                          specified.
+
+                          The "interfaces" keyword must be specified if the class implements
+                          one or more local interfaces. The "interfaces" keyword must not be
+                          specified if the class does not implement local interfaces.
+
+                          The named class is looked up from the location specified in the
+                          "source" keyword.
+
+    Example classlist:
+
+    # BUILTIN
+    java/lang/Object id: 0
+    java/lang/Cloneable id: 1
+    java/lang/String
+
+    # UNREGISTERED
+    Bar id: 3 super: 0 interfaces: 1 source: /foo.jar
+
+
+[3] Identifying the loader_type of archived classes in the shared dictionary
+
+    Each archived Klass* C is associated with a SharedDictionaryEntry* E
+
+    BUILTIN:              (C->shared_classpath_index() >= 0)
+    UNREGISTERED:         (C->shared_classpath_index() <  0)
+
+[4] Lookup of archived classes at run time:
+
+    (a) BUILTIN loaders:
+
+        Search the shared directory for a BUILTIN class with a matching name.
+
+    (b) UNREGISTERED loaders:
+
+        The search originates with SystemDictionaryShared::lookup_from_stream().
+
+        Search the shared directory for a UNREGISTERED class with a matching
+        (name, clsfile_len, clsfile_crc32) tuple.
